BR® 6747-1NC

BR® 6747-1NC and BR® 6747-1NCB

BR® 6747-1NC and BR® 6747-1NCB  primers are one-part, non-chromated, modified epoxy primers which contains no volatile organic compounds (VOCs). Primers are 100% water-based and do not rely on exempt solvents to achieve zero VOC level rating. They exceed all state and federal VOC emission regulations for structural adhesive bonding primers and offer mechanical properties and corrosion resistance equal to that of solvent-based primer systems. BR® 6747-1NCB contains an alternate biocide that is compliant with EU regulations. 

 

BR® 6747-1NC and BR® 6747-1NCB provide outstanding performance with most 250°F (121°C) - 350°F (177°C) curing adhesive systems. Service temperature is from -67°F (-55°C) to 350°F (177°C).

BR® 6747-1NC and BR® 6747-1NCB offer wide application/processing latitude, simple processing with High Volume Low Pressure (HVLP) or standard air atomizing spray equipment and are insensitive to spray booth conditions - temperatures from 65°F - 90°F (18°C - 32°C) and relative humidity from 30% - 70%.

 

Typical applications include bond primer for aluminum components where corrosion protection is critical, corrosion inhibiting paint primer for aluminum substrates, and effective adhesion promoter for other metals (stainless steel, titanium, and nickel).
